The consumption of asparagus results in the release of methanethiol and S-methyl thioesters metabolites in the urine. To some people, these metabolites have a very distinctive odor, but others cannot detect the odor ("asparagus anosmia"). How common is asparagus anosmia?
In a genetic study aiming to find the genetic markers supporting the phenotype, researchers contacted 6909 participants in a large scientific cohort and found that 4161 had asparagus anosmia. Assuming that the cohort is representative of the American adult population, obtain a 90% confidence interval for the true population of Americans with asparagus anosmia. Use technology, for instance, the 1-PropZInt function in the TI graphing calculator or the Statistics / Proportion / 1-sample function (Confidence Interval tab) on CrunchIt!.

Answers

Answer:

The 90% confidence interval for the true population of Americans with asparagus anosmia is (0.5926, 0.6120).

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

Researchers contacted 6909 participants in a large scientific cohort and found that 4161 had asparagus anosmia.

This means that [tex]n = 6909, \pi = \frac{4161}{6909} = 0.6023[/tex]

90% confidence level

So [tex]\alpha = 0.1[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.1}{2} = 0.95[/tex], so [tex]Z = 1.645[/tex].

The lower limit of this interval is:

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.6023 - 1.645\sqrt{\frac{0.6023*0.3977}{6906}} = 0.5926[/tex]

The upper limit of this interval is:

[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.6023 + 1.645\sqrt{\frac{0.6023*0.3977}{6906}} = 0.6120[/tex]

The 90% confidence interval for the true population of Americans with asparagus anosmia is (0.5926, 0.6120).

On a certain IQ test, eleven people averaged a 101.5. A certain reality TV star took
the test and the average fell to 98.04. What is their IQ?

Answers

Answer:

59.98

Step-by-step explanation:

To find the average of a set of numbers, we sum them all together and divide them by the size of the set. Here, we start out with 11 IQ scores. We don't know what they are, but we can still set up an equation with the information we do have. Let's call the sum of those 11 score s. The average must be s/11, which we know is 101.5. With that, we can set up and solve and equation for s:

[tex]\dfrac{s}{11}=101.5\\s=101.5(11)\\s=1116.5[/tex]

Let's call the score of the reality TV star r. If we add their score to the set, we now have 12 scores. The sum of those scores is gonna be the sum of the previous scores, 1116.5, plus the reality TV star's score, r. To find the average, we divide the sum by 12. Finally, we're told that this average is exactly 98.04. Putting all of this into an equation gives us

[tex]\dfrac{1116.5+r}{12}=98.04[/tex]

We can now solve for r algebraically, first by multiplying both sides by 12:

[tex]1116.5+r=98.04(12)\\1116.5+r=1176.48[/tex]

And then subtracting 1116.5 from both sides:

[tex]r=1176.48-1116.5\\r=59.98[/tex]

let the points scored by a girl=x

points scored by a boy=y

7x+2y=46

7x-2y=38

add

x=84/14=6

7×6+2y=46

2y=46-42=4

y=4/2=2

The gypsy moth is a serious threat to oak and aspen trees. A state agriculture department places traps throughout the state to detect the moths. When traps are checked periodically, the mean number of moths trapped is only 0.7, but some traps have several moths. The distribution of moth counts is discrete and strongly skewed, with standard deviation 0.8.
A) What are the mean and standard deviation of the average number of moths x in 60 traps?
B) Use the central limit theorem to find the probability (±0.01) that the average number of moths in 40 traps is greater than 0.4.

Answers

Answer:

a) The mean is 0.7 and the standard deviation is 0.1033.

b) 99.11% probability that the average number of moths in 40 traps is greater than 0.4.

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

When traps are checked periodically, the mean number of moths trapped is only 0.7, but some traps have several moths. The distribution of moth counts is discrete and strongly skewed, with standard deviation 0.8.

This means that [tex]\mu = 0.7, \sigma = 0.8[/tex]

A) What are the mean and standard deviation of the average number of moths x in 60 traps?

60 traps means that [tex]n = 60[/tex]

By the Central Limit Theorem

Mean [tex]\mu = 0.7[/tex]

Standard deviation [tex]s = \frac{0.8}{\sqrt{60}} = 0.1033[/tex]

The mean is 0.7 and the standard deviation is 0.1033.

B) Use the central limit theorem to find the probability (±0.01) that the average number of moths in 40 traps is greater than 0.4.

40 traps means that [tex]n = 40[/tex]

Mean [tex]\mu = 0.7[/tex]

Standard deviation [tex]s = \frac{0.8}{\sqrt{40}} = 0.1265[/tex]

This probability is 1 subtracted by the pvalue of Z when X = 0.4. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{0.4 - 0.7}{0.1265}[/tex]

[tex]Z = -2.37[/tex]

[tex]Z = -2.37[/tex] has a pvalue of 0.0089

1 - 0.0089 = 0.9911

99.11% probability that the average number of moths in 40 traps is greater than 0.4.

Which of the following shows the prime factorization of 200 using exponential notation?

Answers

Answer:

The prime factorization of 200 using exponential notation is [tex]2^{3}\times 5^{2}[/tex].

Step-by-step explanation:

First, we decompose the number given on statement by applying prime numbers in ascending order. We see that 200 is an even number, therefore, we infer that smallest prime number within is 2.

1) [tex]\frac{200}{2} = 100[/tex] (Even number)

2) [tex]\frac{100}{2} = 50[/tex] (Even number)

3) [tex]\frac{50}{2} = 25[/tex] (Even number)

4) [tex]\frac{25}{5} = 5[/tex] (Odd number, not a multiple of 3, but a multiple of 5 since last digit is 5)

5) [tex]\frac{5}{5} = 1[/tex] (Odd number, not a multiple of 3, but a multiple of 5 since last digit is 5)

Now, we construct the prime factorization using exponential notation:

[tex]200 = 2^{3}\times 5^{2}[/tex]

The prime factorization of 200 using exponential notation is [tex]2^{3}\times 5^{2}[/tex].
